The following command is sufficient to build a compiler for the i386
platform (from inside cmd.exe):


fpc -FUlib -otestpp.exe -FE. -Fusystems -Fui386 -Fux86 -Fii386 -di386 pp.pas


"-FUlib" specifies that all *.o and *.ppu files are generated in
directory "lib" (which you need to create first)
"-otestpp.exe" specifies that the resulting executable should be named
"testpp.exe"
"-FE." tells the compiler that the resulting executable should be
created in teh current directory
"-FuXXX" are the directories which contain other used units
"-FiXXX" specifies directories which contain include files
"-di368" will generate a compiler for "i386". Other possibilities can be
seen in the comments of pp.pas


If you have already compiled the compiler using the Makefile ("make all"
in the top level directory of the FPC source or "make cycle" in the
directory of the compiler) then you can use the "manually" created
compiler to compile itself again using the following command:


testpp.exe -n -Fu{YOURSOURCEDIRECTORY}\rtl\units\i386-win32 -B -FUlib
"-otestpp2.exe" "-FE." -Fusystems -Fui386 -Fux86 -Fii386 -di386 -vinw pp.pas


"-n" tells the compiler not to use its default configuration file
The parameter containing {YOURSOURCEDIRECTORY} is the directory where
the Makefile (see above) compiled the RTL (RunTime Library) to (we need
that now that we don't use the default configuration).
"-B" tells the compiler to recompile all units.
We also use a different name, as "testpp.exe" can not be overriden while
it's running.
"-vinw" tells the compiler to display general information (like
"Compiling blabla.pas"), notes and warnings (this is normally also
included in the default configuration).
